INFRAORBITAL NERVE SENSORY DISTURBANCES IN RELATION TO ZYGOMATIC COMPLEX
FRACTURES: A RETROSPECTIVE STUDY

Soh CL, Alia Nadira A, Nur Syahida R
Objective: To determine the prevalence and recovery of infraorbital nerve sensory
disturbances following the occurrence of zygomatic complex fractures. Materials and
methods: 61 patients from 2017 to 2019 who sustained zygomatic complex fractures and
received treatment at a tertiary care centre in Malaysia were recruited for this study. The
patterns of the fractures were reviewed and classified using the classification proposed
by Zing et al. Infraorbital nerve disturbances were recorded before and after treatment.
Results: 21 patients (34.4%) developed infraorbital nerve disturbances following trauma.
16 patients (26.2%) were treated via open reduction and internal fixation (ORIF) and 5
patients (8.2%) via conservative management. Patients who sustained Type C fractures
that reported infraorbital nerve disturbances numbered 11 cases (41.7%) while Type B
fractures numbered 10 cases (37.9%) After 3 months, 11 patients treated via ORIF and 1
patient treated conservatively reported recovery of the infraorbital nerve sensation. The
more serious the fracture displacement is, the worse the prognosis with regards to
infraorbital nerve recovery. ORIF of severe fracture displacement may improve the
outcome of the infraorbital nerve recovery following zygomatic complex trauma.
Conclusion: The prevalence of infraorbital nerve sensory disturbances following the
occurrence of zygomatic complex fractures was 34.4% (21/61 patients).
